Hoene.

To all fte/1,0m il' may eminem 't .known that I, FREDERICK Km'nyacitizen of the United States, residing'at Union, in the ,coiinty'o'tUnion and State of New Jersey, have invented certain new and ,iisefiillinproveinents in Radiator an" Radiator-'Sections-Tlierefor for Auto*mobiles and the like: and I do hereby' declare the tollowingto beaffiill, clear, and

" This-invention llias reference7 generally, to

iniipr'oveniente in radiators and india-torremtions therefor which areused more espe eially upon. automobiles, motoiveaie, and 'vehioleS ofsimilar character, liiit which may be employed also with other classesof ma ohinery and aiparatiises Where itisdesiralile to cool liqiiifeand. fluids of tlie various kindsil'm in which the operation may beieversedytlie'devioe in that ease being used for heating fluids and thelike.

ators, flows circuitously from the upper water-space Within' eachradiator-section, into andlthrough the'niarginal side-spaces andthevbottomspace from between the Walls of eacli radiator-section, aswill be clearly understood. The said front and end-walls of eachradiator-section are also provided in the upper portion oi the space`with suitably disposed'stays or reinforcing posts, as 12and 13, and inthe lonf'er portion of the said space 8 with suitably d l stays orreinforcing posts, 1-1 ano aid stays 12, y123), le and 15 l elng 'pre leholo lon', as shown, an

f and posts 12 surround or enc members or elemeirts` as laterally acrossthe space nected With the said Wolff, form integral portions "i fimembers or elements 16 made with a plurality of holes or per rrations l?which provide suitable inlets for ie purposes to ,ich extend and arecon- 3 and f5. so as to rhe said be presently more fully set tor-'lrlike manner, the said stays or posts surround or encircle other tubularmourners or elements 18, similar to the members or elements 16, saidmembers or elements 18 extending laterally across the lower portion ofthe space 8 and being connected "W'li the said Walls 2 and 3, so as tolio in integ nl portions of the said Walls. The sa :l members orelements 18 are also made with a plurality ot holes or perforations 19which provide suitable outlets, for the purposes to be presently'described.

In the upper portion voi' each radiator-section there are usually twooi? such tubular members or elements 16, While in the lower portion ofeach radiator-section there are usually three of such tubular members orelements 18. From an inspection ot 3 of the drawings, it will beevident, that in the extreme upper Vportion of each radiatorsection, andextending across the space between the walls 2 and 3, is'another tubularmember or element' 20, said member or eletions 21 which provide suitableinlets for the purposes to be presently more fully specified.

As shown more particularly in Fig. 3 of the drawings, it will be seenthat the thin connecting walls 9, by means ofovhich the diagonalarrangement of conveying ducts or passageways l0 and 11 are provided,and the laterally= extending cooling passages or Ventilating ducts areformed, are angularly arranged, as at Q2 and 23, so that taperingopenings which are of larger cross-section at the front and rear facesof the said radi- :iter-section, than at the points midway betweenV saidfront and rear faces, softhatincreased radiating and cooling surfacesare provided.

In order to construct radiator-sections of the general characterhereinset forth, and to assemble any number of such sections in vtheform of a complete radiator having a maximum radiating or coolingsurface with relation to a minimum spaceoccupied by a radiator, and toprovide radiator-sections haring no soldered or otherwise connectedjoints or parts, it is necessary that each radiator-section must be madein one integral piece, and that the various wall-portions oit thesections must be extremely thin;

and. furthermore, the various diagonal ducts and the laterally extendingopenings in each section being so closely located, that it will beimpossible toproduce a radiator-section ot this type by Ithe ordinarymethod of casting, the method empY )yod is necessarily by theelectro-deposition of metal, such as copper or other electrolyticallydeposited metal.

Ono method or manner of producing,r such electrolytically depositedstructure is described iny my former application for Letters-Patenttiled April 10th, 1909, Serial Xumber 489,178, and briefly is as`follows: lnto a suitable inold of steel,I iron, or other suitablematerial, I pour an easily fusible metal or alloy, the melting point olwhich is below the boiling point of Water, so as to produce a solidmetal core, formed with a multiplicity'of holes or openings, conformingto the general shape and configuration of the, radiator-section desired.After re- .mo'slng the metal pattern, which has thus been produced, fromthe mold, the same isv suspended, asa cathode, in an electroplating bathof the proper density and temperature. A deposit of copper. or othersuitable metal,

is thereupon madeupon the surfaces of the said pattern; and, after adeposit of the reouired thickness has been made upon said alloy-pattern,so as to form a skin or envelop about the same, the plated pattern orThe assembled radiator-sections, of which there may be any desirablenumber, may beY placed in suitable frame-like members 62 and G3, whichare suitably' connected by means of screws 64, or other suitablefastening devices, the member 63 being suitably flanged, as at 65', forsecuring the entire device upon the frame-work of an automobile, or toany other fixture.

F rom the foregoing description it will be seen, that a radiator, andradiator-sections therefor, have been produced in which all the parts ofeach section are made in one integral piece, thereby avoiding the greatcost of 'assembling a great many small parts and the securing togetherof such parts by means of solder. A hollow or chambered'radiator-section isvalso produc-ed having the interior thereof studdedIwith a great many hollow members which are ,very closelyv placedtogether, and which extend from and form integral portions of thejside-,walls of the radiator-section, so that the interior of eachsection is i''ormed with a multiplicity otv closely locatedI*liter-conveying' ducts, and with a multiplicity of intermediatelyplaced air-ducts leading from one side to the other side of theradiator-section, and thereby providing a maximum radiating surface.
